  • Electrochemistry Encyclopedia Extracting metals from

    Flotation is also used to split copper and nickel sulfides and separate them from iron sulfides and gangue minerals. Cobalt sulfides appear in the nickel concentrate and the cobalt is subsequently recovered. Flotation has developed from the treatment of simple ores to the ever more complex ones that are being found today.
